In iscsi_check_tmf_restrictions() task->hdr is dereferenced to print the
opcode, it is possible that task->hdr is NULL.
There are two cases based on opcode argument:
1. ISCSI_OP_SCSI_CMD - In this case alloc_pdu() is called
after iscsi_check_tmf_restrictions()
iscsi_prep_scsi_cmd_pdu() -> iscsi_check_tmf_restrictions() -> alloc_pdu().
Transport drivers allocate memory for iSCSI hdr in alloc_pdu() and assign
it to task->hdr. In case of TMF task->hdr will be NULL resulting in NULL
pointer dereference.
2. ISCSI_OP_SCSI_DATA_OUT - In this case transport driver can free the
memory for iSCSI hdr after transmitting the pdu so task->hdr can be NULL or
invalid.
This patch fixes this issue by removing task->hdr->opcode from the printk
statement.

This commit allows setting the RSS hash generation parameters from
ethtool. When setting parameters for a given flow type from ethtool
(e.g. tcp4), all the corresponding flows in the flow table are updated,
according to the supported hash parameters.
For example, when configuring TCP over IPv4 hash parameters to be
src/dst IP + src/dst port ("ethtool -N eth0 rx-flow-hash tcp4 sdfn"),
we only set the "src/dst port" hash parameters on the non-fragmented TCP
over IPv4 flows.

One of the classification action that can be performed is to compute a
hash of the packet header based on some header fields, and lookup a RSS
table based on this hash to determine the final RxQ.
This is done by adding one lookup entry per flow per port, so that we
can configure the hash generation parameters for each flow and each
port.
There are 2 possible engines that can be used for RSS hash generation :
- C3HA, that generates a hash based on up to 4 header-extracted fields
- C3HB, that does the same as c3HA, but also includes L4 info in the hash
There are a lot of fields that can be extracted from the header. For now,
we only use the ones that we can configure using ethtool :
- DST MAC address
- L3 info
- Source IP
- Destination IP
- Source port
- Destination port
The C3HB engine is selected when we use L4 fields (src/dst port).

The PPv2 classifier allows to perform classification operations on each
ingress packet, based on the flow the packet is assigned to.
The current code uses only 1 flow per port, and the only classification
action consists of assigning the rx queue to the packet, depending on the
port.
In preparation for adding RSS support, we have to split all incoming
traffic into different flows. Since RSS assigns a rx queue depending on
the hash of some header fields, we have to make sure that the hash is
generated in a consistent way for all packets in the same flow.
What we call a "flow" is actually a set of attributes attached to a
packet that depends on various L2/L3/L4 info.
This patch introduces 52 flows, wich are a combination of various L2, L3
and L4 attributes :
- Whether or not the packet has a VLAN tag
- Whether the packet is IPv4, IPv6 or something else
- Whether the packet is TCP, UDP or something else
- Whether or not the packet is fragmented at L3 level.
The flow is associated to a packet by the Header Parser. Each flow
corresponds to an entry in the decoding table. This entry then points to
the sequence of classification lookups to be performed by the
classifier, represented in the flow table.
For now, the only lookup we perform is a C2 lookup to set the default
rx queue.

The PPv2 Controller has a classifier, that can perform multiple lookup
operations for each packet, using different engines.
One of these engines is the C2 engine, which performs TCAM based lookups
on data extracted from the packet header. When a packet matches an
entry, the engine sets various attributes, used to perform
classification operations.
One of these attributes is the rx queue in which the packet should be sent.
The current code uses the lookup_id table (also called decoding table)
to assign the rx queue. However, this only works if we use one entry per
port in the decoding table, which won't be the case once we add RSS
lookups.
This patch uses the C2 engine to assign the rx queue to each packet.
The C2 engine is used through the flow table, which dictates what
classification operations are done for a given flow.
Right now, we have one flow per port, which contains every ingress
packet for this port.

PPv2 Controller has 8 RSS Tables, of 32 entries each. A lookup in the
RXQ2RSS_TABLE is performed for each incoming packet, and the RSS Table
to be used is chosen according to the default rx queue that would be
used for the packet.
This default rx queue is set in the Lookup_id Table (also called
Decoding Table), and is equal to the port->first_rxq.
Since the Classifier itself isn't active at any time for the moment,
this doesn't have a direct effect, the default rx queue at the moment is
the one where all packets end-up into.

There is no RSS_TABLE register in PPv2 Controller. The register 0x1510
which was specified is actually named "RSS_HASH_SEL", but isn't used by
this driver at all.
Based on how this register was used, it should have been the
RXQ2RSS_TABLE register, which allows to select the RSS table that will
be used for the incoming packet.
The RSS_TABLE_POINTER is actually a field of this RXQ2RSS_TABLE
register.
Since RSS tables are actually not used by the driver for now, this
commit does not fix a runtime bug.

- MVPP2_DEFAULT_RXQ * num_possible_cpus if in multi queue mode

Using get_seconds() for timestamps is deprecated since it can lead
to overflows on 32-bit systems. While the interface generally doesn't
overflow until year 2106, the specific implementation of the TCP PAWS
algorithm breaks in 2038 when the intermediate signed 32-bit timestamps
overflow.
A related problem is that the local timestamps in CLOCK_REALTIME form
lead to unexpected behavior when settimeofday is called to set the system
clock backwards or forwards by more than 24 days.
While the first problem could be solved by using an overflow-safe method
of comparing the timestamps, a nicer solution is to use a monotonic
clocksource with ktime_get_seconds() that simply doesn't overflow (at
least not until 136 years after boot) and that doesn't change during
settimeofday().
To make 32-bit and 64-bit architectures behave the same way here, and
also save a few bytes in the tcp_options_received structure, I'm changing
the type to a 32-bit integer, which is now safe on all architectures.
Finally, the ts_recent_stamp field also (confusingly) gets used to store
a jiffies value in tcp_synq_overflow()/tcp_synq_no_recent_overflow().
This is currently safe, but changing the type to 32-bit requires
some small changes there to keep it working.
